Resumen:
|
RY Tau is a rapidly rotating classical T Tauri star observed close to edge-on. The combination of new HST/STIS observations obtained in 2001 with HST/GHRS archive data from 1993 has allowed us to get, for the first time, information on the thermal structure and velocity of the wind. The repeated observations of the S III] and C III] lines show a lack of changes with time on the blue side of the profile ( dominated by the wind contribution). Very high temperature plasma (log T-e = 4.8) is detected at densities of 9.5
